臺灣博碩士論文加值系統

本論文主旨在研製一組高功率隔離型雙向直流-直流轉換器，應用於電網與電池間兩端做為能量調節。轉換器分為前後兩級電路，電池端功率級架構為交錯式降/升壓轉換器，電網端為三相串聯諧振轉換器。前級架構以兩組降/升壓型電源轉換器組成，如此可以分散電流路徑降低功率元件上的電流，同時將兩組開關控制信號以180°的相位差控制兩相之功率開關，如此能夠有效降低輸入與輸出電流的漣波。後級架構是三臂六開關的全橋型轉換器，具有三組變壓器和三組諧振槽，每一臂控制信號相位各差120°，並操作於串聯諧振區間。三組變壓器一次側和二次側都使用Y形接法，相較於一般全橋式轉換器，三相全橋式轉換器的變壓器平均分擔總輸出功率，如此能夠減小鐵芯體積。
本論文實際完成一台輸出功率20 kW的原型電路，並以數位訊號處理器TMS320F28035來實現數位控制，在不同負載下轉換效率均在90 %以上。

In this thesis, an isolated high-power bi-directional DC-DC converter is studied and implemented. The prototype circuit consists of two stages of bidirectional DC-DC converters. The stage attached to the battery-side is an interleaved buck/boost converter, and the stage of the grid-side is a three-phase series resonant converter. The battery-side stage consists of two buck / boost converters, so the load current can be shared by these two circuits. Consequently, it can reduce the stress of the switch elements. Besides, the switching control signals of the two converters have a phase-shifted of 180° each other, so it can effectively reduce the output current ripple. The grid-side stage mainly consists of three half-bridge legs i.e. there are six switches. There are three isolated transformers and three resonant tanks, the control signal for each leg has a phase-shift of 120° with each other. This converter stage is operated as a series resonant converter. The three isolated transformers are Y-connected on both the primary and secondary sides. Compared with conventional single-transformer full-bridge configuration, the developed scheme can share the output power with three transformers, and the size and cost of each transformer are thus reduced.
In this thesis, a prototype circuit with 20 kW rated power has been built and tested. A digital-signal processor chip TMS320F28035 is used to realize the controller of this converter. The measured efficiencies are all higher than 90 % within the full range of load conditions.
